A typical buck converter in a PC motherboard may include per phase: three N-channel MOSFETs in a DPAK package and one driver IC in a SO8 package. By replacing these components with the highly integrated FDMF6700, designers save more than 80 percent of board space, said Fairchild. Another benefit of the integration of components in a single package is the elimination of parasitic inductances of board traces and leads of individual discrete package, which will improve overall efficiency.
This family includes the FDMF8700 (8 x 8 mm MLP, 30 A) standard DrMOS module, the FDMF8705 (8 x 8 mm MLP, 18 A) low-current DrMOS module and FDMF6700 (6 x 6 mm MLP, 25 A) ultra-compact DrMOS module.
The FDMF6700 is available in a 40-pin (6 x 6 mm) MLP. These products use lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All Fairchild products are designed to meet the requirements of the European Union's Restriction of the Use of (certain) Hazardous Substances (RoHS) directive.
Pricing: $2.50 each in quantities of 1,000.
